specific Embodiment
[0045] The implementation process of embodiment 1-12 is shown in the table below:
[0046]
Embodiment 1
[0047] Filling gas in embodiment 1 is air, and the sample that injects in the glass container 12 is distilled water, after placing the sample to be irradiated for 8 days, the sample to be irradiated is connected to the gas chromatograph, and its gas chromatogram is as follows image 3 Shown: Gas chromatography shows that the micro-area of hydrogen gas (microvolt*second) is 263.3, and the concentration in the air is 0.054%. After standardization, the volume of hydrogen gas in the air sample is 0.000101ml (under one standard atmospheric pressure), and the hydrogen gas is Mass is 9.1×10 -9 g, the number of moles of hydrogen is 4.55×10 -9 mol. This amount of hydrogen is the amount of hydrogen in the gas above the distilled water sample in the glass container that has been placed for 8 days.
Embodiment 2
[0048] The gas chromatogram that embodiment 2 obtains, as Figure 4 As shown, the hydrogen microarea (microvolt*second) in the radiation gas is 122535.3, and the hydrogen concentration is 22.29%. After standardization, the hydrogen volume in the radiation gas sample is 0.0471ml (under one standard atmospheric pressure), and the hydrogen mass is 4.24 ×10 -6 g, the number of moles of hydrogen is 2.12×10 -6 mol. The above shows that the amount of hydrogen in the air is greatly increased after the yellow sea water filled with air is irradiated.
